Reading HW signature...FAIL(ack) G965F/DS
 

Hi,

I have a G965F/DS that is frozen mck. When it boots it shows "SIM Network Pin blocked. Enter SIM Network PUK".

I am seeing the error mentioned in the title. I have toggled nearly every option on ******, but nothing works. How come I keep getting this error?

Thanks in advance!

I had same problem with a samsung a520f. I had set mtp+adb, and dm+modem+adb, but the problem has been not solving. I made a factory reset, then it worked perfectly.
